How can the two Hadiths be reconciled, which mention the varying distances between the levels of Paradise, where one mentions "as between the heaven and the earth" and the other mentions "a hundred years"?

The distance between the heaven and the earth, whether it is one hundred or five hundred years, presents no contradiction due to the varying speed of travel. Thus, seventy or one hundred years signifies fast travel, while five hundred years denotes slow travel. The estimation of distance is intended to facilitate understanding.
